How can I change the form used to print tasks? I would like it to print more than one line of notes.
The standard form for printing a single task is the memo style, which will print as many notes as you like. I’m going to guess that your problem is actually with printing the table style (multiple tasks), in which case Outlook can’t do anything for you natively.
Your best bet would be to either get a third-party reporting tool like Seagate’s “Crystal Reports” or create a report in Microsoft Word and merge into it.
The Crystal Reports solution is probably easier, because the Word solution probably will involve some programming to access the Tasks.
